SERIES CONCEPT

Under general supervision, the Scanner performs or supervises the 
scanning, measuring, and analyzing of particle physics events which are 
recorded on film or in emulsion; and performs other related duties as 
required.

Incumbents examine stereoscopic vievs of particle physics events, 
detect, identify, classity, and prepare for measurement various 
categories of events; which may include ten categories, according to 
criteria established for the particular experiment; scan emulsions under 
a microscope to identify interesting particle physics events, orient 
events in emulsion, and make calculations; audit and compare the results 
of previously scanned film; locate vertex and tracks of designated 
events and operate a digitizer to measure and record each track which 
nay include measuring the tracks of complex particle physics events 
where the background tracks, number of tracks, or interpretation of the 
vertex and ending of tracks require a basic understanding of the physics 
principles involved; record decisions regarding categories; key punch 
data; and perform technical analysis of data which entails making 
mathematical calculations and plotting figures.

Performance of the above duties normally require that incumbents have 
academic training in the sciences including course work in physics, 
mathematics, and chemistry.

                        CLASS CONCEPTS

Supervising Scanner I

Incumbents supervise the work of two or more full-time-equivalent 
Scanners.  In addition to supervisory duties, incumbents typically 
perform technical analysis of data normally requiring an understanding 
of the scientific principles involved and the making of mathematical 
calculations requiring an understanding and application of higher 
mathematics which is acquired through course work in trigonometry, 
geometry, or basic physics.  Incumbents may also write subroutines for 
complex computer program systems or write simple programs.

Scanner II

Incumbents scan, measure, and perform basic analysis of particle physics 
events which are recorded on film or in emulsion.  This is the full 
operational level within the series and the majority of scanning duties 
are performed at this level.

Scanner I

Incumbents measure particle physics events and perform the less 
difficult scanning duties.  The scanning work is comparatively simple or 
is performed under the close supervision of a higher level Scanner.  The 
measuring of events may be performed without close supervision.  This 
class is the entry level in the Scanner series.

                    MINIMUM QUALIFICATIONS

Supervising Scanner I

Two years of college as a science major including course work in 
physics, mathematics, and chemistry, and two years of experience as a 
Scanner including at least six months as a Scanner II; or an equivalent 
combination of education and experience.

Scanner II

Two years of college as a science major including course work in 
physics, mathematics, and chemistry; or graduation from high school and 
one year of experience as a Scanner 1; or an equivalent combination of 
education and experience.

Scanner I

Graduation from high school with course work in geometry, trigonometry, 
or elementary physics; or an equivalent combination of education and 
experience.
